I am having issues programming/reading some titan radios. I purchased all the software and cables from Midland a few years ago. Programmed the radios originally and all was fine. Went to change some things and cannot read any of them. I have 1 UHF low power dash mount, 1 VHF low power dash mount and 1 VHF highpower remote mount. All do the same thing and fail on read. Anyone else have issues with these ? Do I need a old PC like the MOT stuff ? I thought I used a PC with XP to program them, but cannot confirm this either
